成层坡积结构构造特征、粒度、化学、电镜扫发描分析和测年资料揭示其形在于末次冰期间冰段（６００００ａＢＰ～４４０００ａＢＰ）。存在由湿冷向干冷的气候变化。成层坡积上覆的坡积黄土则代表末次冰期全盛及全新世环境以显著干冷为特征。此剖面突出表明昆仑山垭口地区末次冰期早期不是干冷，而是湿冷，与季风模式不吻合。故只能认为当时该区受西风带影响。
Tectonic features, grain size, chemical and electron microscopic scanning analyzes and dating data reveal that the shape of the stratigraphic pentad structure lies in the ice segment during the last ice period (60000 aBP ~ 44000 aBP). There is a change from wet to dry and cold climate. The slope-plot loess overlying stratigraphic slope represents the fact that the Gregorian and Holocene environments of the last glacial period were characterized by significant dryness. The profile highlights that the early Kunlun Mountains Pass area is not dry and cold in the early period of the last glacial ice, but is wet and cold, which is inconsistent with the monsoon pattern. It can only be considered that the area was affected by the westerlies.
